Carleman estimates were first introduced in the pioneering work of Carleman
[1]}. Since then they have been actively used for proofs of
uniqueness and stability results for ill-posed Cauchy problems, see, e.g.
books [2]}, [3]}, [4]}. Carleman estimates were introduced in the field of
Coefficient Inverse Problems in the publication [5]} initially
with the single goal of proofs of uniqueness theorems. Since then the idea
of [5]} became popular, see, e.g. [7]}, [8]}, [3]}, [10]}, [11]}, [12]}, [13]}, [14]}. The convexification principle
represents an extension of the idea of [5]} to the topic of
globally convergent numerical methods for CIPs. Those numerical methods
might be generalized and employed for important applications like cloaking
and quantum scattering studied in [16]}, [17]}.
